Ernie and Bert plan to go to the zoo tomorrow, but Ernie can't make up his mind. What would happen if Ernie bought a balloon, but then lost it when he gets frightened by a buffalo? Then he remembers that the zoo is closed on Wednesdays. (EKA: Episode 0172)
Ernie wants Bert to pretend to be mad, but Bert says that he can't, because he has nothing to feel angry about. Ernie asks Bert to pretend that he borrowed Bert's paper clip collection, and dropped it into the sewer while playing with it. The thought makes Bert really mad. Bert gets tired out, and tells Ernie that he can't get mad anymore. Ernie makes a confession -- he really did lose Bert's favorite paper clip collection.
